heavier than air type which may be caused to slowly ascend from itssupport and when the desired elevation has been reached to travel in anydirection desired.

A further object of the invention is to provide a flying machine havinga hull portion of such size as to form a cabin for the operators and thepower mechanism.

the invention consists of the .improved fly A further. object of theinvention is to provide a flying machine'having an elevating propellerand a traversing propeller adjustable to direct the hull portion in anydirection desired.

A further object of the invention. is to provide a flying machine inwhich the power mechanism is conveniently arranged for easy control instarting, stopping, or reversing the mechanism.

A further object of the invention is to provide a flying machine whichis of simple construction, is strong and durable and is well adapted forthe pn ose desired.

With the above and o er objects in view ing machine and-its parts andcombinations as set forth in the claims, and all equivalents thereof. I

In the accompanying drawin in which the same reference charactersmdicate the same parts in all of'the views:

Fi tion view of the improved flying machine;

Fig. 2 is a horizontal sectional view taken online 22 ofFig.1;

Fig. 3 is an enlarged detail sectional v ew of the reversing mechanismof the flying machine; a

, Fi 4 is a transverse sect onal view thereof taien on line'4-4 of Fig.3; and

Fi 5 is a transverse sectional view thereon on line 55 of Fig. 3.Referring to the drawings the numeral 8 indicates the hull, frame orcabin which is.

of rectangular form in cross section and havmg pomted bow and stern ends9 and 10.

The cabin is provided with windows 11, a

door 12 and runners or supports 13.

v A driving shaft 14 extending vertically through a medial portion ofthe cabin has an ascending propeller 15 mounted on its upper end and asupporting plate 16 firmly mounted on its lower end. The shaft 14isJournaled in bearings 17, 18, 19 and 20 and the bearings 18 and 20 areof the ball type to take the end thrust of the shaft. Bearing 17 ispositioned above the cab-in and is connected thereto by angularlyextending brace rods 21.

Two internal combustion engines 22 are mounted in the cabin and have ageared connection 23 with the vertically'extending shaft 14 and drivethe same. Both engines are connected to both propeller mechanisms in amanner to permit the use of either one or both engines thus providing'asafety fac-- tor in the event of one of the engines accidentallystopping. the engine have frictionclutch connections 25 with the gearedconnection-23 controlled by operating levers 26. The shaft 14 also hasmounted thereon and forming part of one of the gears of'the gearconnection 23, a bevel gear 27 which is in mesh with a bevel gear 28mounted on a horizontally extending counter shaft 29. One'end of thehorizontal shaft is journaled in the bearing 19. and the other orforward end is journaled in a bracket bearing 30 mounted in the forwardportion of the cabin. A vertical shaft 31 having its lower end restingin a step bearing 32 is also journaled in the bracket bearing 30 andextends upwardly through the roof of the cabin and is provided with abevel gear 33 on its upper end.,. The vertical shaft 31 also hasjournaled thereon two beveled reversing gears 34 and 35 which are re 1is a' longitudinalvertical sec-' on the forward end of the horizontalshaft 29.

The two shafts 24 of The inner faces of the bevelgears 34 and Y 35 arerecessed as indicated by the numerals 34' and 35"to receive the expandirtions 37 of a double clutch 38spline on the said vertical shaft 31.This clutch is actuated by a forked bellfcranked lever 39 which has alinked connection 40 with an operating lever 41 pivoted on, the bracketearing When the clutch member is moved up- 100 in mesh with a bevel gear36 mounted fast wardly the upper gear 35 will drive the vertical shaft31 and when moved downwardly the lower gear 34 will drive the saidvertical shaft in a reverse direction.

The body portion 41 of the clutch which-is splined to the shaft isformed with heads 42 having recessed portions 43 of V-shape in crosssection to receive the expanding portions 37 of the clutch and maintainsaid expanding portions slidably in position.

The upper end portion of the vertical shaft 31 extends through and hasits bearing in the depending sleeve 44 of a revoluble casing 45 mountedon the upper forward end portion of the cabin. The sleeve 44 isjournaled in bearings 46 and 47 and at its lower end portion has a wormwheel 48 keyed fast thereon which is in mesh with a worm 49 mounted on ashort shaft 50. Said short shaft is journaled in portions of thebearings 30 and 47 and is revolved by a hand wheel 51 for steering theflying machine. I

A horizontally extending shaft 52 journaled in the revoluble casing 45has a bevel gear 53 mounted on its inner end which is 1n mesh with thebevel gear 33of the vertical shaft 31 and is revolved thereby. Apropeller 54 mounted on the forward end portion of the propeller shaftis rotated topropel the machlne forwardly or rearwardly and thepropeller may be swung at an angleto the cabin to steer the machine inany direction desired.

In operation the ascending propeller is rotated to raise the machme fromthe ground and when raised the propeller 54 is rotated to propel themachine forwardly or rearwardly and to steer the machine in anydirection desired. When it is desired to descend the speed of rotationof the u per or ascending plropeller is decreased su ciently to permit te machine to slowly descend by gravity.

From the foregoing description 'it will be seen that the flying machineis of ve simple construction and is well adapted for the purposedescribed. a

What I claim as my invention is:

- 1. A flying machine, comprising a frame in the form of a cabin, anengine within the cabin, a shaft extending upwardly through the cabinand having a propeller mounted the upwardly extending shaft, anothershaft located adjacent one end of the cabin and extending upwardlythrough the cabin, a

counter shaft having a geared connection" with the first mentionedupwardly extending shaft and a clutch and geared connection with theshaft adjacent the end of the cabin, said last mentioned clutch andgeared connection providing for rotating the shaft adjacent the end ofthe cabin 1n opposite directions, a casing journaled on the lastmentioned shaft and having a depending sleeve which surrounds the same,a horizontally extending shaft journaled in the casing and having ageared connection with the ad acent shaft, a propeller mounted on thehorizontally extending shaft, and a worm and worm wheel'means mountedwithin the cabin for turning the sleeve.

2. A flying machine, comprising a frame in the form of a cabin, anengine within the cabin, a shaft extending upwardly through the cabinand having a ropeller mounted on its upper end, angularly extendingbrace rods connectedto the cabm and the upper portion of the shaft, abevel gear and clutch driving connection between the engine and'theupwardly extending shaft, another shaft located adjacent one end'ofthe cabin and extending upwardly through the cabin,

.a counter shaft having a geared connection with the first mentionedufwardly extend ing shaft and a clutch an geared connection with theshaft adjacent the end of the cabin, said last mentioned clutch andgeared connection providing'for rotating the shaft adjacent the end ofthe cabin in opposite directions, a bell crank lever and link connectionfor actuating the clutch, a casing jo'urnaled on the last mentionedshaft an having a depending sleeve which surrounds the same, ahorizontally extending shaft journaled in the casing and having a gearedconnection with the adjacent shaft, a propeller mounted on thehorizontally extendmg shaft, and a worm and worm wheel means mountedwithin thecabin for turn in the sleeve.

n testimony whereof, I aflix my slgnature.
